Preparation

Whisk together while slowly adding the oil. You need to drizzle in the oil very slowly while stirring constantly, as if you were making a mayonnaise

Add the ground meat, shallots, parsley, chives and capers

Add salt and pepper to taste

Mix together well and serve

Suggestion

Like any self-respecting Belgian, the only possible accompaniments to your steak tartare are French fries and a beer.
As for the capers, I recommend that you use very small ones, as they are easier to mix in.
